Multi-mission module..."pod"

Between missions, Commanding Officers may dock at a starbase (Obsidian Command or a TF starbase) and swap their pods for one of the others. By default, new Nebula class vessels in Obsidian Fleet come equipped with the tactical pod.

Sensor pod: The majority of the first Nebula-class ships were outfitted with this pod, which greatly extended the ship's sensor range. With this pod the Nebula-class ship is virtually unmatched in regards to sensor capability. Ships with this pod module were routinely assigned to deep-space exploration, hostile border patrols or long-range reconnaissance.

Weapons pod: With the recent Borg invasions and Dominion War, Starfleet quickly mobilized to deploy the weapons pod, which contains 8 forward-facing "pulse" torpedo launchers, and 3 Type X point-defense phaser emitters. The launchers are fed by an additional 200 photon torpedoes stored in the pod itself. The weapons pod is also equipped with two shield generators (one main, one backup), since it was realized that the pod would be an easy target. The shield generators are the same type used through-out the rest of the ship, and draw power directly from the auxiliary energy reserves during Red Alert situations.

Tactical pod: This is a late 2370s addition to the Nebula-class fleet, and is quickly becoming the default module for all new Nebulas being built. The design combines the scanning capabilities of the sensor pod and the offensive capabilities of the weapons pod into one module. There are disadvantages to this design. The tactical pod contains 75 fewer torpedoes (125) and only three torpedo launchers - two forward, one aft - in order to make room for the sensor pallets. Also, the scanners are primarily designed to aid in targeting for the torpedoes and phasers, and as such are not optimized for long-range usage.

Hospital pod: This specialty pod, while not found in wide-spread use, includes the same medical facilities found in large starbases and is equipped to handle several hundred casualties at once.

Habitation/Colony pod: This pod contains a large number of residential quarters, and is sometimes used on long-term missions, or on missions focusing on populating a colony. Depending on configuration, up to 6,000 people can be ferried in the habitation module. With slight modifications, this module can be configured to act as a troop transport, enabling the ship to carry several thousand troops. This module also contains a dozen dedicated transporters, allowing the roughly 5,000 troops to be beamed out within a relatively short amount of time.

Shuttlebay/Hangar pod: This experimental pod includes a large shuttle hangar with the space to hold a significant quantity of fighters and runabouts. A typical Hangar pod would contain the following:
